Surgically induced scleral necrosis

Bilateral streptococcal corneoscleritis complicating beta irradiation induced scleral necrosis.

Comment 5-FU is an antimetabolite which interferes with normal cell mitosis. It interfers with the S phase and the G2 phase of the cell cycle which correspond, respectively, with the synthesis of DNA and cellular components required for mitosis.' As corneal epithelial cells are constantly undergoing replication they are particularly susceptible to its toxic effects. Reduction of dosage has been...

Pseudomonas endophthalmitis associated with scleral necrosis.

Three cases of pseudomonas endophthalmitis associated with scleral necrosis 3 to 10 years after pterygium excision and beta irradiation are described. The value of prophylactic repair of radiation-induced scleral necrosis and early aggressive management of pseudomonas endophthalmitis are emphasized.

Radiation scleral necrosis simulating early scleromalacia perforans.

Surgically Induced Astigmatism Assessment

The article “Surgically Induced Astigmatism Assessment: Comparison Between Three Corneal Measuring Devices” by Ofir et al.1 was effective in demonstrating equivalence between three anterior corneal measuring devices (Lenstar LS900, Haag-Streit, Koeniz, Switzerland; IOLMaster 500, Carl Zeiss Meditec, Dublin, CA; and Atlas topographer, Carl Zeiss Meditec) by assessing the vectorial astigmatism ch...

Surgically Induced Astigmatism.

To the Editor: We read with interest the article by Ofir et al.1 In 70 eyes, the authors used three devices to evaluate surgically induced astigmatism (SIA) in eyes undergoing cataract surgery with temporal 2.4-mm clear corneal incisions. Vector analysis was used appropriately to calculate the SIA in each eye.2 However, when reporting the median and mean of the SIA in the whole group, the autho...
