We report a case of bilateral cataract surgery performed in a 21-year-old western lowland gorilla. Phacoemulsification with intraocular lens insertion was performed using standard human surgical equipment. Visual function significantly improved. She subsequently mated and gave birth. Ultimately, cataract surgery enabled the birth of a baby gorilla.

The authors report a case of a human-habituated mountain gorilla, Alvila, resident at the San Diego Zoo, who was found to have a herniated intervertebral lumbar disc after being attacked by the gorilla troop's silverback male gorilla. Ultimately, the gorilla required surgical intervention for her disease and made a full recovery. To our knowledge, this is the only known case of spine surgery. A 36-year-old female human-habituated mountain gorilla (Gorilla beringei beringei), resident at the San Diego Zoo, was noticed by caregivers to walk with a substantial limp after being attacked by the gorilla troop's silverback male gorilla. Magnetic resonance (MR) imaging of her lumbar spine revealed a large herniated disk at the L1-2 level on the right. This finding appeared to correlate well with the gorilla's symptoms. The gorilla underwent a lumbar diskectomy under loupe. Post-operatively the gorilla did very well. The right leg weakness was immediately improved post-operatively. The gorilla continued to "crutch walk" initially, swinging on the upper extremities and not bearing weight on the lowers. However, by 2 weeks the limp was no longer noticeable to the zoo caregivers. The wound healed well and there was no evidence of wound infection or CSF leak. The gorilla was reunited with her troop and has reintegrated well socially. With 10 months of follow-up, the gorilla continues to do well. This is the only known case of spine surgery in a gorilla. For best surgical results, one needs to consider the similarities and differences between the gorilla and human vertebral anatomy. We believe that careful pre-operative planning contributed to the good early post-operative result. Ultimate assessment of the long-term outcome will require additional follow-up.

STUDY DESIGN: A case report is presented. OBJECTIVE: To describe a case of severe symptomatic lumbar stenosis in an adult gorilla successfully treated with decompressive surgery. SUMMARY OF BACKGROUND DATA: Although spinal degenerative disease is thought to be less common in apes than in humans, gorillas and bonobos are known to have higher rates of disease than other African apes. METHODS: A 42-year-old female gorilla presented with a history of progressive lower extremity weakness. She was unable to ambulate normally or climb, pulling herself around with her arms. Her keeper did not believe she was incontinent. Physical examination revealed that ankle plantarflexion and dorsiflexion were absent on the right and weak on the left. Radiographs revealed disc space narrowing with osteophytes at the last mobile segment. Myelogram and computed tomography revealed severe spinal stenosis at the last two mobile segments. Under general anesthesia, a standard laminectomy and bilateral lateral recess decompression were performed. RESULTS: There were no anesthetic or wound complications. The gorilla was noted to have improved ankle strength bilaterally on postoperative day 1. On postoperative day 3, the animal began to walk and climb. At 20 months, the animal is back to her neurologic baseline. CONCLUSIONS: Symptomatic lumbar degenerative disease with neurologic compromise may be treated surgically, with excellent outcome, in the adult gorilla. Though this is an unusual situation, knowledge that this is a potentially reversible condition may benefit other gorillas in captivity.

Two juvenile, male, captive-born lowland gorillas (Gorilla gorilla gorilla) with the same father but different mothers developed bilateral cataracts. The cataracts were surgically removed within 6 yr and 3 mo, respectively, of diagnosis, and foldable intraocular lenses were implanted. Although vision was not restored in one eye with a mature, 6-yr-old cataract in gorilla A, surgical intervention on the other eye was performed before a complete cataract developed, and vision was fully restored. Gorilla B was treated at the age of 17 mo, and normal visual development proceeded in both eyes. This animal developed bilateral after-cataract and therefore needed a second intervention in both eyes using Nd:YAG laser treatment. The genetic component of juvenile cataracts should be considered in breeding management programs.

A juvenile female mountain gorilla (Gorilla beringei beringei) of the Mubare tourist group in Bwindi Impenetrable National Park, Uganda, developed a severe, complete rectal prolapse that did not spontaneously resolve. Eight months prior, a juvenile female mountain gorilla of the Mubare group developed a mild, complete rectal prolapse that resolved spontaneously within 24 hr. Field guides reported that spontaneously resolving prolapses had been seen previously in two other juveniles, one of which was from the Mubare group. The tissue became increasingly necrotic and maggot infested over the course of 1 wk. Surgical intervention involved amputation of the affected rectal tissues and suturing the viable portion to the anal sphincter muscle with simple interrupted absorbable sutures. The surgery was performed in the field in accordance with Uganda Wildlife Authority policies. Antibiotics and anthelmintics were administered systemically, and the gorilla returned to the group. The gorilla appeared to recover fully after 3 wk. Histology of the resected rectal tissue confirmed intense inflammation and necrosis with myiasis but did not reveal an underlying etiology.

A mature lowland gorilla (Gorilla gorilla) in the Los Angeles Zoo had destroyed 3 successive infants. To avoid a recurrence, active intervention was instituted during its 4th pregnancy. The period of gestation was estimated by physical examination, radiography, and amniocentesis. Intrauterine growth was followed by serial ultrasonographic cephalometry. When fetal maturity was achieved, as determined by amniotic fluid phospholipid profile, the fetus was delivered by cesarean section.
