This study shows that microperimetry can be a useful tool for objective evaluation of macular function and progression of the disease.

An analysis of ocular firecracker injuries in five consecutive years during a festive season in a tertiary eye care hospital in South India, Expert Review of Ophthalmology, 11:3, 235-240, ABSTRACT Background: To analyse the presentation of ocular firecracker injuries during a festival celebration in five consecutive years. Methods: We retrospectively analysed 541 patients with cracker injuries who presented to a tertiary eye care hospital during the fortnight of Deepavali for five consecutive years. The parameters studied were the age and sex, environmental factors, type of firework, eye involved and whether the involved person was a passer-by or actively involved. Results: Children up to 15 years, males and bystanders were seen to be affected more frequently. The most common firework involved was the flower pots. Conclusions: Fire cracker related ocular injuries are an important public health problem in India where celebrations are not complete without lighting crackers. This study brings to light the importance of safety measures and emphasises the need for restrictive firework legislation which has proved to reduce such injuries in countries across the world.

Peribulbar block, though safe, can cause serious complications such as globe perforation and peribulbar hemorrhage. Hyaluronidase is an enzyme that is used as an adjuvant in peribulbar anesthesia, and it helps in rapid penetration of the anesthetic agent. Hypersensitivity to hyaluronidase is a rare but potentially sight-threatening complication. We report a case of hyaluronidase hypersensitivity following peribulbar injection for cataract surgery mimicking as peribulbar hematoma in the immediate postinjection phase and as orbital cellulitis 48 h later.

A 39-year-old woman with typical retinitis pigmentosa (RP) for 9 years and a positive family history of night blindness was diagnosed with diabetes mellitus (DM). She developed proliferative diabetic retinopathy (PDR) during the course of disease. She was promptly managed with pan retinal photocoagulation (PRP). PDR developing in a case of typical RP is extremely rare and has not been reported in the literature to date. Recognition of this rare, vision threatening complication, points out a definite need to further look deep into the pathogenesis of diabetic retinopathy.
