Intermediate Uveitis with Cystoid Macular Edema as Presentation of Retained Caterpillar Hair in the Vitreous Cavity.

PURPOSE: To report an unusual case of retained caterpillar hair in the vitreous cavity presenting as recurrent Intermediate Uveitis with cystoid macular edema. METHOD: Case Report. RESULTS: A 40-year-old male presented to our uveitis clinic with recurrent episodes of redness and diminution of vision in his left eye for 3 years. He was diagnosed and treated elsewhere as a case of recurrent intermediate uveitis and was referred to our center for a second opinion to initiate immunosuppressive therapy. A detailed history revealed that a caterpillar had fallen into his left eye 3 years back, followed by severe irritation, pain, and redness. He received topical antibiotics and corticosteroids, and retained caterpillar hair was removed from the ocular surface. During the last 3 years, the patient had multiple episodes of inflammation despite being treated with oral and topical corticosteroids. At the current visit, a meticulous clinical examination at our centre revealed multiple, migrated, retained caterpillar hair in the vitreous cavity. The patient was diagnosed with Ophthalmia Nodosa (Type V) and managed with surgical intervention (vitreous surgery). The case highlights an unusual presentation of ON and the role of pars plana vitrectomy in its successful management. CONCLUSION: We highlight a rare and unusual presentation of ophthalmia nodosa and its successful management.

Visual field indices in children and adults with comparable retinal nerve fiber layer thickness.

PURPOSE: To compare visual field indices in normal children and adults with similar retinal nerve fiber layer (RNFL) thickness on optical coherence tomography (OCT). METHODS: This cross-sectional study included 59 eyes of 59 normal children 6-18 years of age compared to normal adults. The children underwent visual field testing on the Humphrey Field Analyzer (HFA) and RNFL thickness measurement on OCT. Normal adults who had undergone OCT and visual field testing were retrieved from the OCT database. The mean deviation (MD) in each child was compared with the MD in RNFL thickness-matched eyes of normal adults. Children 6-11 years and 12-18 years were analyzed separately. RESULTS: Overall, the MD of children was significantly less than that of the normal adults despite having the same RNFL thickness (-2.42 ± 1.42 dB vs -1.61 ± 1.47 dB [P = 0.006]). When stratified by age, the difference in MD of children <12 years was significantly less than normal adults (-2.72 ± 1.5dB vs -1.53 ± 1.2 dB [P = 0.003) while in children >12 years, the difference did not reach statistical significance (-2.18 ± 1.2 vs -1.51 ± 1.32 [P = 0.12]). CONCLUSIONS: In our study cohort, children <12 years had lower visual field indices than adults. Their visual fields may appear worse than they would for an adult with the same RNFL thickness. Normal children >12 years of age seem to have a retinal sensitivity comparable to the adult normative database. It is worthwhile to consider the development of a separate pediatric normative database for the visual field assessment of children <12 years of age.

Mitigation of traumatic blepharoptosis with "central levator tuck": A novel approach in upper eyelid repair.

PURPOSE: Complex upper eyelid lacerations can present to the emergency department after a myriad of trauma. The goal of the surgical repair is anatomical and functional recovery along with symmetrical cosmesis. Despite meticulous surgery, post traumatic blepharoptosis may develop. We describe an additional step during upper eyelid laceration repair to help mitigate the development of traumatic blepharoptosis. METHODS: Patients with traumatic eyelid laceration without head injury, globe injury or associated orbital fractures, who were planned for a primary upper eyelid repair were included. Intraoperatively, wound margins and tissues were identified to establish anatomical continuity. After the LPS muscle was reinserted onto the tarsus, a single, central suture LPS plication - the "central levator tuck" was performed. This helped in improving the muscle action as well as strengthening its reattachment onto tarsus. RESULTS: Four cases underwent laceration repair with this modified technique. The nature of eyelid injury, surgical technique, and the outcome at 6 months is described. Three patients had a successful outcome, whereas one patient developed early scarring which reduced with scar therapy over time. CONCLUSION: We describe a simple and effective "central levator tuck" technique for traumatic eyelid laceration repair with optimal functional and cosmetic outcome while reducing the development of blepharoptosis in four patients.

Primary chondromyxoid fibroma of the orbit: An orbital mass with calcification.

Primary orbital chondromyxoid fibroma is a rarely reported entity. A 34-year-old lady presented with painless, non-axial proptosis of the left eye of 6 months duration. Orbital imaging showed a supero-temporal mass with calcific foci and bone erosion. The mass caused globe compression resulting in choroidal folds. Anterior orbitotomy with complete mass excision was performed. The histopathology revealed a chondromyxoid fibroma. At 12-months follow-up, the patient is doing fine with no clinical recurrence. Chondromyxoid fibroma is an important differential diagnosis for bony orbital tumors.
