Biopsy pathology in uveitis |
p. 261 |
Jyotirmay Biswas, Radha Annamalai, Vaijayanthi Krishnaraj DOI:10.4103/0974-9233.90126 Uveitis is fraught with speculations and suppositions with regard to its etiology, progress and prognosis. In several clinical scenarios what may be perceived as due to a systemic infection may actually not be so and the underlying etiology may be an autoimmune process. Investigations in uveitis are sometimes the key in identification and management. Invasive techniques could be of immense value in narrowing down the etiology and help in identifying the cause. This article updates one on the invasive techniques used in biopsy such as anterior chamber paracentesis, vitreous tap and diagnostic vitrectomy, iris and ciliary body biopsy, choroidal and retinochoroidal biopsy and fine needle aspiration biopsy (FNAB). In populations where certain infections are endemic, the clinical scenario does not always respect a known presentation and the use of biopsy is resorted to as a sure way of confirming the etiology. Biopsies have a role in diagnosis of several inflammatory and infectious conditions in the eye and are pivotal in diagnosis in several dilemmas such as intraocular tumors and in inflammations. Appropriate and timely use of biopsy in uveitis could enhance the diagnosis and provide insight into the etiology, thus enabling precise management. |

Update in pathological diagnosis of orbital infections and inflammations  |
p. 268 |
Vincent B Lam Choi, Hunter K.L Yuen, Jyotirmay Biswas, Myron Yanoff DOI:10.4103/0974-9233.90127 Orbital infections and inflammations include a broad spectrum of orbital diseases that can be idiopathic, infectious, from primary or secondary inflammatory processes. Being able to properly diagnose and manage these orbital diseases in a timely manner can avoid permanent vision loss and possibly save a patient's life. When clinicians are faced with such patients, quite often the exact diagnosis cannot be made just based on clinical examination, various laboratory tests and imaging are needed. Moreover, orbital biopsies with histopathological analyses are often required, especially for the atypical cases. Thus, it is important for the clinicians to be familiar with the pathological features and characteristics of these orbital diseases. This review provides a comprehensive update on the clinical and pathological diagnosis of these orbital infections and inflammations. |

Update on pathologic diagnosis of corneal infections and inflammations |
p. 277 |
Geeta K Vemuganti, Somasheila I Murthy, Sujata Das DOI:10.4103/0974-9233.90128 One of the most frequent types of corneal specimen that we received in our pathology laboratory is an excised corneal tissue following keratoplasty. Several of these cases are due to corneal infections or the sequelae, like corneal scar. Advances in the histological and molecular diagnosis of corneal infections and inflammations have resulted in rapid and accurate diagnosis of the infectious agent and in the overall understanding of the mechanisms in inflammatory diseases of the cornea. This review provides an update of histopathological findings in various corneal infections and inflammations. |

Femtosecond laser-assisted cataract surgery: A current review |
p. 285 |
Majid Moshirfar, Daniel S Churgin, Maylon Hsu DOI:10.4103/0974-9233.90129 To evaluate the safety, efficacy, advantages, and limitations of femtosecond laser-assisted cataract surgery through a review of the literature. A PubMed search was conducted using topic-appropriate keywords to screen and select articles. Initial research has shown appropriate safety and efficacy of femtosecond laser-assisted cataract surgery, with improvements in anterior capsulotomy, phacofragmentation, and corneal incision. Limitations of these studies include small sample size and short-term follow-up. Cost-benefit analysis has not yet been addressed. Preliminary data for femtosecond laser-assisted cataract surgery shows appropriate safety and efficacy, and possible advantage over conventional cataract surgery. Questions to eventually be answered include comparisons of long-term postoperative complication rates-including infection and visual outcomes-and analysis of contraindications and financial feasibility. |

Combined viscocanalostomy-trabeculectomy for management of advanced Glaucoma- A comparative study of the contralateral eye: A pilot study |
p. 292 |
Tarek M Eid, Waleed A Tantawy DOI:10.4103/0974-9233.90130 Purpose : To compare combined viscocanalostomy-trabeculectomy (VISCO-TRAB) to trabeculectomy (TRAB) for the management of advanced glaucoma.
Materials and Methods : The study cohort comprised of 18 subjects with bilateral advanced glaucoma who underwent VISCO-TRAB surgery (VISCO-TRAB group) in the right eye and TRAB (TRAB group) in the left eye. VISCO-TRAB constituted lamellar scleral flap, deep scleral flap dissection with deroofing of Schlemm's canal (SC), viscodilation of SC, penetrating trabeculectomy, peripheral iridectomy, and tight flap closure. All eyes received subconjunctival mitomycin. Success criteria included intraocular pressure (IOP) < 14 mmHg or > 30% lowering of IOP with no devastating complications. A P value less than 0.05 was considered statistically significant.
Results : Mean IOP was significantly lower after VISCO-TRAB compared to TRAB at 1 week and 3 months postoperatively (P<0.05). No eyes lost more than two lines of Snellen acuity. There were more hypotony-related complications after TRAB than VISCO-TRAB surgery. Target IOP was achieved in 83.3% in the VISCO-TRAB group compared to 55.6% in the TRAB group.
Conclusion : Combined VISCO-TRAB is effective in reducing IOP to the target level for advanced glaucoma with lower postoperative complications. |

Oral propranolol for the treatment of periorbital infantile hemangioma: A preliminary report from Oman |
p. 298 |
Beena Harikrishna, Anuradha Ganesh, Sana Al-Zuahibi, Samia Al-Jabri, Ahmed Al-Waily, Adil Al-Riyami, Faisal Al-Azri, Feraz Masoud, Abdullah Al-Mujaini DOI:10.4103/0974-9233.90131 Purpose : To investigate the efficacy and safety of oral propranolol in the management of periorbital infantile hemangioma in four subjects.
Materials and Methods : Consecutive patients who presented with periorbital capillary hemangioma with vision-threatening lesions were prospectively enrolled in this study between January 2009 and October 2010. All subjects underwent treatment with 2 mg/kg/day oral propranolol. All subjects underwent ocular, systemic, and radiologic evaluations before treatment and at periodic intervals after starting therapy. Side effects from therapy were also evaluated.
Results : Four subjects, between 3 months and 19 months of age, with periorbital hemangioma were enrolled in this study. Two subjects had been previously treated with oral corticosteroids with unsatisfactory response. All subjects had severe ptosis, with the potential for deprivation amblyopia. Three subjects had orbital involvement. After hospital admission, oral propranolol was initiated in all subjects under monitoring by a pediatric cardiologist. Subsequent therapy was performed with periodic out-patient monitoring. All subjects had excellent response to treatment, with regression of periorbital and orbital hemangioma. There were no side effects from therapy.
Conclusions : Oral propranolol for periorbital hemangioma was effective in all the four subjects. Oral propranolol may be appropriate for patients who are nonresponsive to intralesional or systemic steroids. In patients with significant orbital involvement and lesions causing vision-threatening complications, oral propranolol can be the primary therapy. |

Oestrus ovis as a cause of red eye in Aljabal Algharbi, Libya |
p. 305 |
Manal Z.M Abdellatif, Hesham M.F Elmazar, Amna B Essa DOI:10.4103/0974-9233.90133 PMID:22224020Purpose : To study the common presenting signs of external ophthalmomyiasis caused by Oestrus ovis larvae in Aljabal Algharbi province, Libya.
Materials and Methods : A prospective non- comparative study was conducted from September 2009 to July 2010 at the Gharian outpatient clinic, Gharian, Aljabal Algharbi, Libya. The common presenting features of patients with external ophthalmomyiasis and data on the organism that caused the disease were collected.
Results : Twenty one cases diagnosed with external ophthalmomyiasis were recorded. There were fourteen males (66.67%) and seven females (33.33%) in the cohort. The mean age was 14.29 ± 3.46 years (range, 8 years to 22 years: males; 13.39 ± 3.03 years and females; 16.67 ± 3.75 years). The main complaint was redness (100.00%), itching (71.43%) and tearing (57.14%). Twelve patients (57.14%) were from rural areas and 9 patients (42.9%) were from urban areas. The causative organism was found to be first instar of Oestrus ovis larvae.
Conclusion : External ophthalmomyiasis caused by Oestrus ovis can cause red eye in patients from Aljabal Algharbi, Libya and requires careful examination to ensure early diagnosis and proper treatment. |

Photodynamic therapy of symptomatic choroidal nevi |
p. 309 |
Luis Amselem, Kaan Gündüz, Alfredo Adan, Melisa Zişan Karslıoğlu, Amanda Rey, Noelia Sabater, Xavier Valldeperas DOI:10.4103/0974-9233.90134 Purpose : To evaluate the role of photodynamic therapy (PDT) for patients with symptomatic choroidal nevi involving the fovea or located near the fovea with subretinal fluid extending to the fovea.
Materials and Methods : Retrospective review of five patients who underwent PDT for choroidal nevi at two separate centers in Ankara and Barcelona.
Results : The mean initial logMAR visual acuity was 0.5 (range: 0 to 1.5). The mean largest tumor base diameter was 3.2 mm (range: 2.1-4.5 mm) and the mean tumor thickness was 1.1 mm (range: 0.7-1.6 mm). The mean number of PDT sessions was 1.6 (range:1-3). The mean final tumor thickness was 1.0 mm (range: 0-1.6 mm) at a mean follow-up of 19 months (range: 12-32 months). The mean final logMAR visual acuity was 0.4 (range: 0-1.5). Subfoveal fluid disappeared or decreased significantly in 4 of 5 eyes (80%) after PDT.
Conclusions : PDT led to resolution of subretinal fluid with preservation of visual acuity in many symptomatic choroidal nevi in this study. Careful case selection is important as PDT of indeterminate pigmented tumors may delay the diagnosis and treatment of an early choroidal melanoma and thereby increase the risk for metastasis. |

p. 314 |
Abdullah Aoun Al-Qahtani, Hailah Al-Hussain, Imtiaz Chaudhry, Sahar El-Khamary, Hind M Alkatan DOI:10.4103/0974-9233.90135 Liposarcoma is a malignant tumor of adipose tissue. Considered the most common soft tissue sarcoma in adults, orbital liposarcoma is extremely rare. Most cases of orbital liposarcoma are primary and rarely metastatic. We report two cases of primary orbital liposarcoma with clinical presentation, radiologic studies (available for one case), and detailed histopathologic features. A brief review of primary orbital liposarcoma is also presented. |

Histopathologic findings in two cases with history of intrastromal corneal ring segments insertion |
p. 317 |
Mohammad Al-Amry, Hind M Alkatan DOI:10.4103/0974-9233.90136 Intrastromal corneal ring segments (INTACS) implantation for mild myopia or keratoconus is simple and effective in most cases. Rarely, major complications can occur due to implantation. In this case report, we present two examples of possible intraoperative and postoperative complications of INTACS. The first case had histopathologic documentation of Descemet's membrane perforation as an intraoperative complication and the second case had accumulation of foamy histiocytes along the lamellar channels which has not been previously reported. These complications suggest further study is required on the long term effect of INTACS implantation on corneal tissue. |

Lacrimal gland fistula after upper eyelid blepharoplasty |
p. 326 |
Mohsen Bahmani Kashkouli, Abtin Heirati, Farzad Pakdel DOI:10.4103/0974-9233.90139 To report the first case of lacrimal gland fistula after upper eyelid blepharoplasty for blepharochalasis. Standard upper blepharoplasty and the hooding excision were performed in a female with blepharochalasis. The patient developed a fistulous tract with tearing from the incision few days after hooding excision. Fistula excision and lacrimal gland repositioning were performed. There were no complications after the repositioning procedure (6 months follow up). Prolapsed lacrimal gland and fistula formation can occur after upper blepharoplasty hooding excision. |

Lacrimal glands: Size does matter! |
p. 328 |
Suyash Mohan, Amogh Hegde, CC Tchoyoson Lim DOI:10.4103/0974-9233.90140 A 40-year-old woman presented with vague headaches and blurred vision. Contrast-enhanced magnetic resonance imaging of the brain revealed bilaterally symmetrical diffuse enlargement of the lacrimal glands. A fine needle biopsy of the lacrimal gland was consistent with sarcoidosis. Although, isolated lacrimal gland involvement is rare, it may be the initial clinical presentation of sarcoidosis, as seen in this patient. Imaging plays a vital role in these unsuspected cases and careful evaluation of the lacrimal glands with dedicated thin section, fat suppressed, axial and coronal orbital imaging, may help identify a pathological cause and avoid a delay in diagnosis. |

Surgical treatment and histopathology of a symptomatic free-floating primary pigment epithelial iris cyst in the anterior vitreous |
p. 331 |
Eman Al-Kahtani, Hind M Alkatan DOI:10.4103/0974-9233.90141 We report the surgical removal of an iris pigment epithelial cyst that was floating freely in the posterior chamber of an 18-month-old child. The reason for surgical removal was disturbance in near vision secondary to the movement of the cyst across the visual axis. Visual disturbance secondary to a unilateral anterior vitreous iris cyst at this age is a rare presentation and, to the best of our knowledge, has not been reported previously as an indication for surgery. We performed histopathological study of the cyst aspirate to determine its contents and its possible origin. |

Visual disturbance as the first symptom of chronic myeloid leukemia |
p. 336 |
Philemon K Huang, Srinivasan Sanjay DOI:10.4103/0974-9233.90143 Chronic myeloid leukemia (CML) is a well-studied entity and advances made in diagnosis and treatment have improved the disease outcome. Patients with ophthalmic manifestation of CML have been reported to have lower 5-year survival rates. Hence, recognizing the early fundus changes may improve outcome by allowing earlier diagnosis and treatment. We report a case of a previously healthy 30-year-old Myanmarese male, who presented with a minor visual disturbance, complaining of seeing a 'black dot' in his left visual field for the past 1 week. Fundoscopic examination revealed bilateral retinal blot hemorrhages, white-centered hemorrhage, and preretinal hemorrhage over the left fovea. The full blood count and peripheral blood film were abnormal, and bone marrow biopsy confirmed the diagnosis of CML. Cytoreduction therapy was promptly commenced and his symptoms resolved, with improvement in visual acuity. No complications were recorded at 1-year follow-up. |
