The most common variations of imagery rehearsal therapy (IRT) "relate to the number of sessions, duration of treatment, and the degree to which exposure therapy is included in the protocol". Medication
Prazosin (alpha-1 blocker) appears useful in decreasing the number of nightmares and the distress caused by them in people with PTSD. Risperidone (atypical antipsychotic) at a dosage of 2 mg per day, has been shown in case series to remission of nightmares on the first night. Trazodone (antidepressant) has been shown in a case report to treat nightmares associated with a depressed patient.Trials have included hydrocortisone, gabapentin, paroxetine, tetrahydrocannabinol, eszopiclone, xyrem, and carvedilol.

Chromosomal abnormalities are only a minority of cases of anophthalmia. Postnatal diagnosis
MRI/CT
MRIs and CTs can be used to scan the brain and orbits. Radiologists use this to assess the internal structures of the globe, the optic nerve and extraocular muscles, and brain anatomy. Examination
Physicians, specifically ophthalmologists, can examine the child and give a correct diagnosis. Some will do molecular genetics tests to see if the cause is linked with gene mutations. Genetic testing can include chromosomal microarray analysis, single-gene testing, or multigene-panel testing. Genomic testing including exome sequencing, genome sequencing, and mitochondrial sequencing may be considered if single-gene testing or use of a multigene panel fails to confirm a molecular diagnosis. Associations
There are a few conditions that are associated with Anophthalmia. These include:
Trisomy 13
Lenz Syndrome
Goldenhar-Gorlin Syndrome
Waardenburg syndromeAside from these associative conditions, anophthalmia in only one eye tends to be associated with complications in the other eye. These risks include a higher chance of having glaucoma or a detached retina. Treatments
Prosthetic eye
Currently, there is not a treatment option for regaining vision by developing a new eye. There are, however, cosmetic options so the absence of the eye is not as noticeable. Typically, the child will need to go to a prosthetic specialist to have conformers fitted into the eye. Conformers are made of clear plastic and are fitted into the socket to promote socket growth and expansion. As the childs face grows and develops, the conformer will need to be changed. An expander may also be needed in anophthalmia to expand the socket that is present.
