After losing the sight in his right eye as the result of an infection, Lawrence Berrell sued Stephen M. Hamilton, M.D. and Eye Consultants of Atlanta, P.C. for medical malpractice. In a highly detailed and well-reasoned order, the trial court awarded summary judgment to the defendants. Among other findings, the court determined that Berrell failed to offer proof of causation. Although Berrell contends that the trial court erred, we find otherwise and affirm. On appeal from the grant of summary judgment, this Court conducts a de novo review of the evidence. Entertainment Sales Co. v. SNK, Inc. , 232 Ga. App. 669 502 SE2d 263 1998. In so doing, we must construe the evidence and all reasonable inferences therefrom in favor of the nonmoving party. Chiaka v. Rawles , 240 Ga. App. 792 525 SE2d 162 1999.
When so considered, the evidence shows that Berrell had a medical history of bilateral glaucoma and underwent several eye surgeries and treatments over a four-year period. Berrell had glaucoma laser treatment of the right eye in July 1994. He also had glaucoma laser treatment on his left eye in August 1994 and again in January 1995. In August 1996, a retinal detachment repair was performed on his right eye. In January 1998, Dr. Hamilton, a board certified ophthalmologist, removed a cataract, replaced it with an implant lens, and performed a trabeculectomy on his right eye. A trabeculectomy or “bleb” is an operation in which a hole is created to drain intraocular fluid and relieve intraocular pressure caused by glaucoma. Although alleviating vision-threatening pressure, the bleb leaves a patient more susceptible to infection entering the eye.
