Clinical implications of energy used in Neodymium: Yttrium Aluminum Garnet posterior capsulotomy on intraocular pressure.

Purpose: To study the trend of the rise of intraocular pressure (IOP), with the energy used during Neodymium: Yttrium Aluminum Garnet (Nd: YAG) posterior capsulotomy.

Methods: This is a prospective interventional study undertaken at a tertiary care center. The study was conducted on 221 non-glaucomatous eyes that underwent Nd: YAG posterior capsulotomy, of which 181 patients completed the study.

Von Hipple-Lindau: Unusual case presentation with peripheral and juxtapapillary retinal hemangioma.

Von Hipple-Lindua (VHL) syndrome is an autosomal dominant neoplastic disorder in which multiple benign or malignant tumours and cysts develop in central nervous system and visceral organs. Retinal capillary hemangioma is the most frequent and often the earliest manifestation of VHL syndrome. We report a case with multisystemic involvement diagnosed as a case of multiple endocrine neoplasia (MEN) syndrome but the presence of multiple, unilateral peripheral and juxtapapillary retinal capillary hemangioma was able to clinche the definative diagnosis of VHL and thus helped in appropriate management of the patient.

Comparison of 30-2 Standard and Fast programs of Swedish Interactive Threshold Algorithm of Humphrey Field Analyzer for perimetry in patients with intracranial tumors.

Purpose: To find out whether 30-2 Swedish Interactive Threshold Algorithm (SITA) Fast is comparable to 30-2 SITA Standard as a tool for perimetry among the patients with intracranial tumors.

Methods: This was a prospective cross-sectional study involving 80 patients aged ≥18 years with imaging proven intracranial tumors and visual acuity better than 20/60. The patients underwent multiple visual field examinations using the two algorithms till consistent and repeatable results were obtained.

Tonometry and Care of Tonometers.

Intraocular pressure (IOP) remains the only modifiable risk factor in the management of glaucoma. Hence, IOP and its appropriate measurement deserve our ongoing interest. Over the years, not only has our understanding of glaucoma changed but also has changed our approach to the measurement of the IOP.
