Aims:In this study, we have tried to assess the success rate and difficulties that we came across while performing the transcanalicular endoscope combined laser-assisted dacryocystorhinostomy (T-ECLAD).Materials and Methods:A prospective study of 60 patients suffering from nasolacrimal duct obstruction confirmed by preoperative syringing was carried out at the Regional Institute of Ophthalmology. T-ECLAD is a new minimally invasive dacryocystorhinostomy procedure, which is performed by diode laser (980 nm diode laser with power of 10 watts) through lacrimal canaliculi with the help of a cannula and fiber optic cable. The interior of the nasal cavity was visualized with the help of the nasal endoscope on a monitor. Success of procedure was assessed by patency of the lacrimal drainage system on irrigation.Results:We performed 56 successive T-ECLAD. The average procedure time was 10 min, and on an average 235 Joules of laser energy was needed. We observed a patent nasolacrimal duct on irrigation in 39 out of 56 treated eyes. 1 patient had partial, 5 patients had blocked irrigation, and 10 patients did not return for follow up. This yields a success rate of 69.6% (if we exclude patients who did not return for follow up) with an average follow-up period of 6 months.Conclusions:The 980-nm T-ECLAD is a new contribution to the field of lacrimal surgery. It is a minimally invasive and quick procedure.

IOP readings obtained by an I-care tonometer in our study have shown reasonable concordance with GAT. Overestimation of IOP measured by RT as compared with GAT is directly proportional to the IOP. As the I-care tonometer measured IOP with good accuracy, it may be considered as an appropriate method for clinical use in normal subjects and glaucoma patients.

Purpose:The purpose of the study is to evaluate the long-term changes in intraocular pressure (IOP) after extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens (PCIOL) implantation versus phacoemulsification with PCIOL implantation in otherwise normal cataract patients in India.Materials and Methods:The study was conducted in the Department of Ophthalmology, King George's Medical College, Lucknow between August 2000 and August 2001. One hundred and seventeen eyes of 115 patients were included in the study. 84 patients were randomly selected for ECCE with PCIOL implantation (ECCE group) and 31 patients were selected for phacoemulsification with PCIOL implantation (Phaco group). IOP was measured pre-operatively and post-operatively, from the 1st month to the 12th month. Statistical significance was indicated by P > 0.05.Results:There was a mean fall in IOP of 2.70 mm Hg (19.74%) in the ECCE group and 2.74 mm Hg (20.57%) in the phaco group. The decrease in the mean post-operative IOP from baseline was statistically significant (P > 0.01) at the end of 2 months in both groups. There was no statistically significant difference in post-operative IOP at any visit between groups (P < 0.05, all post-operative visits). After 4th monthpost-operatively, the IOP was mostly stable, but it was significantly lower than the pre-operative IOP.Conclusion:Significant IOP reduction may be expected after cataract surgery with either ECCE or phacoemulsification with IOL implantation. The lowering of IOP became statistically significant at about 2 months post-operatively, but became almost stable after the 4th month.

Abstract

Spectacle-related glass foreign body eye injury is commonly associated with sports activities and a significant contributor to penetrating eye injury. Optically clear glass particles may easily be missed during the examination. We present a case of intrastromal glass foreign body embedded in superficial layers of corneal stroma associated with sports-related spectacle injury in a 21-year male. There were multiple superficial lacerations and multiple small glass fragments on the surface of the cornea. After the removal of glass fragments under a slit lamp, the eye was washed thoroughly and patched with antibiotic and cycloplegic eye drops for twenty-four hours. However, the next day we could detect a small intrastromal glass fragment in the superficial layers of the corneal stroma under slit-lamp examination with high magnification. A small piece of glass (1mm in length) was removed under topical anaesthesia.
