Accumulation of formic acid as metabolite of methanol causes mitochondrial dysfunction that can reduce ATP synthesis rate, disrupt axoplasmic transport, and elevate the reactive oxygen species (ROS). All of these mechanisms lead to the death of retinal ganglion cell (RGC) and optic nerve. RGC destruction in MTON has similar patterns with those that have been observed in glaucoma, ischemia, and trauma cases, that is through excessive activation of glutamate neurotransmitter via N-Methyl D-Aspartate receptors (NMDAR). Memantine is a NMDAR antagonist that inhibit the ion channel of NMDAR. This inhibitory effect of NMDAR by memantine is expected to reduce intracellular calcium level, prevent apoptosis of RGC, and prevent further mitochondrial dysfunction. Caspase-9 is essential to eliminate cells by executing apoptotic Objective: To observe the effect of Memantine on Caspase-9 level of RGC in Methanol-Intoxicated Rats. \u0000Methods : This experimental study was performed on 28 Methanol-Intoxicated Rats that are assigned into four treatment groups: K1 (MTON;enucleated day-3), K2 (MTON+Memantine; enucleated day-3), K3 (MTON; enucleated day-7), and K4 (MTON+Memantine; enucleated day-7). During the experiment, all groups were exposed to N2O:O2 gas and were given methanol orally. Caspase-9 level of RGC were measured immediately after enucleation. \u0000Results : The average of Caspase-9 level (ng/ml): K1=197,88±33,98; K2=205,64±63,66; K3=243,15±40,13; K4=150,08±119,60.

Upon initial examination the vision was 6/9 with normal IOP. The object obstructed the view of the entry site, therefore corneal wound was suspected. CT scan showed penetrating metal object without posterior segment involvement. Anti-tetanus injection, topical and oral levofloxacin were given. He underwent exploration, foreign body removal and repair surgery. During surgery, the wound was revealed as a scleral laceration, 4 mm from nasal limbus. One day post-operative, vision was 6/20.

This study aims to evaluate the recent studies on topical treatment for dry eye disease related to SS and provide evidence based recommendation for clinical practice. \u0000Methods : Electronic literature search was performed through the PubMed and Cochrane database from the last 10 years.
